Footnotes:
t When using the Division SA/DA tables, the correct SAlDA ratio for permanent pool sizing should be computed based upon the
actual impervious °!o and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
z In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
Il. REQUIRED ITEMS CHECKLIST

basin is specified prior to use as a wet detention basin.
m. A mechanism is specified which will drain the basin for maintenance or an emergency.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check one) 0 does0'do not incorporate a vegetated filter at the outlet.
This system (check one) 0 does oes not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 399 Page 2 of 4

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at feast monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e.
stockpiling near a wet detention basin or strearn, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3•'75 feet in the forebay, the sediment shall be removed.

Dear Ms.:Naugle:
We received, on February 4, 2008,• your letter of January 26,,,2008 which',,
had .an attached email' from, you to the' "•writer ' dated January :17; 2008.
Apparently, you .had failed_ • to review the package that was hand -delivered to
your -office on January 25, 2008 responding to previous comments.
Your letter of January 26, 2008 lists• six '(6) -items of which'the first ,four
(4) ' are indicated.by _hand written' . notes -.that ,they- have been received by- DWQ.
Comment number 5 is indicated as "'need" by hand written comment. This
letterand, attachments .will, address that comment.
Enclosed, please find a• revised and .6kecuted "B"• attachment for High
Density Residential Subdivisions indicating -the proposed 'restrictive covenants
which will be 'record'ed by the applicant in conjunction with the requirements
of Title 15 NCAC, 2H.1000,' the'Coastal .Stormwater Management: Regulations.
Also. attached ' are two (2) copies- of • the revised Sheet 1, of. 1 of the Overall
Stormwater Plan' for the Hamptons.
The plan has,been revised by contin' wing the lot numbering sequence'for
all of the lots for each class of lot, Estate .(larger) and. Patio '(smaller). ' Since
the lots are all numbered consecutively' and' there are no overlapping lot
-numbers, this should preclude the need for an additional table since
attachment' "B" reflects . the identical information as contained on the overall
` plan. The number of total lots did not•change nor did any other factor.
Earlier lot numbering schemes in ' out• .office, for this project, involved
starting over with the .number one for lots which were to be developed' in the
future due, to the unknown nature. of possible, -future revisions to the master
plan. Brunswick Plantation has, utilized {parallel numbers for- Estate- Lots
.(larger or Custom) and Patio lots (smaller). Some other projects utilize a lot
numbering.system`,where,individual neighborhoods or sections start'at, lot 1
and progress' upward with lot numbers. " ,

Please help me with a few items for the stormwater application;
LIZ The sum of totals for each drainage areas to the eight ponds is
13,068,233 sf [300 acres], whereas the Hamptons overall total
,drainage area reports 14,860,494 sf [341.15 acres] on the
application page 2. Please verify the inconsistent values.
The project area is reported as 268.58 acres on the application in
section III (3), which is different than the drainage area total
of 13,068,233 sf (300 acres], but only 3.2 acres of off -site
drainage is reported to pond 44. Please verify the inconsistent
values.
L',V, The sum of totals for the BUA to eight ponds is 4,735,005 sf;
whereas the Hamptons overall total BUA reports 5,758,632 sf on the
application page 2. Please verify the inconsistent values.
y. Please explain why there is two different column totals on the
(/ last page for application page 2 with one column labeled Phases I
& II and a different column labeled Hamptons overall. If this is
high density and all stormwater is treated as mentioned in your
dated October 1, 2007 in the second to the last paragraph.

Please provide a table of built -upon areas for those lots in Phase.
41 draining to ponds #1-5 with lot numbers and built -upon area in
square feet assigned to each lot. You submitted deed restrictions
for lots 4441-605 with 7,500 sf assigned to each and lots #
822-1201 with 5,000 sf assigned to each, but the BUA breakdown for
the other lots in phase I is needed on a table to be included in

whereas the Hamptons overall total drainage area reports 14,860,494 sf [341.15 acres) on
the application page 2. Please verify the inconsistent values.
2. The project area is reported as 268.58 acres on the application in section 111 (3), which is
different than the drainage area total of 13,068,233 sf [300 acres], but only 3.2 acres of off -
site drainage is reported to pond #4. Please verify the inconsistent, values.
3. The sum of totals for the BUA to eight ponds is 4,735,005 sf; whereas the Hamptons overall
total BUA reports 5,758,632 sf on the application page 2. Please verify the inconsistent
values.
4. Please explain why there is two different column totals on the last page for application page
2 with one column labeled Phases I & 11 and a different column labeled Hamptons overall. If
this is high density and all stormwater is treated as mentioned in your letter dated October 1,
2007 in the second to the last paragraph, then correct the inconsistent values.
5. Please provide a table of built -upon areas for those lots in Phase I draining to ponds #1-5
with lot numbers and built -upon area in square feet assigned to each lot. You submitted
deed restrictions for lots #441-605 with 7,500 sf assigned to each and lots # 822-1201 with
5,000 sf assigned to each, but the BUA breakdown for the other lots in phase I is needed on
a table to be included in the permit.
6. Please note that a revision to one number may have a domino effect on other numbers,
which may require revision of the applications, calculations, supplements, plans, details, and
associated documentation. Please verify all numbers and correct to ensure consistency in
the application documents.
Please note that I sent the attached request to Mr. Jay Houston by e-mail on January 17, 2008,
but have not received a reply. (attached) Please note that this request for additional information is in
response to preliminary reviews. The requested information should be received in this Office prior to
February 11, 2008, or the application will be returned as incomplete. The return of a project,will
necessitate resubmittal of all required items, including the application fee.

Jay;
Please help me with a few items for the stormwater application;
1. The sum of totals for each drainage areas to the eight ponds is
13,068,233 sf [300 acres], whereas the Hamptons overall total
drainage area reports 14,860,494 sf [341.15 acres] on the
application page 2. Please verify the inconsistent values.
2. The project area is reported as 268.58 acres on the application in
section III (3), which is different than the drainage area total
of 13,068,233 sf [300 acres], but only 3.2 acres of off -site
drainage is reported to pond 44. Please verify the inconsistent
values.
3. The sum of totals for the BUA to eight ponds is 4,735,005 sf;
whereas the Hamptons overall total BUA reports 5,758,632 sf on the
application page 2. Please verify the inconsistent values.
4. Please explain why there is two different column totals on the
last page for application page 2 with one column labeled Phases I
& IT and a different column labeled Hamptons overall. If this is
high density and all stormwater is treated as mentioned in your
letter dated October 1, 2007 in the second to the last paragraph.
5. Please provide a table of built -upon areas for those lots in Phase
41 draining to ponds 41-5 with lot numbers and built -upon area in
square feet assigned to each lot. You submitted deed restrictions
for lots #441-605 with 7,500 sf assigned to each and lots ff
822-1201 with 5,000 sf assigned to each, but the BUA breakdown for
the other lots in phase I is needed on a table to be included in
the permit.
Please let me know that you receive this memo.

The Hamptons Phases I & II (formerly Brunswick Plantation North)
Brunswick County
Dear Mr. McLamb:
The Wilmington Regional Office received previously requested information for the pending
modification to the Stormwater Management Permit for The Hamptons Phases I & 11 on
October 3, 2007. A preliminary review of that information has determined that the application
is not complete. The following information is needed to continue the stormwater review:
Please sign, seal and date the revised calculation pages.
2. Where there are errors on the "deemed permitted" plans, the submittal of a
modification allows the Division to require these errors to be addressed. The
forebay volume for the ponds must be that volume between the bottom of each
forebay and the reported permanent pool elevation for the pond it serves, not the
permanent pool elevation for the forebay. An example of this is Pond #1, whose
permanent pool elevation is 34.0. The calculations, however, use 34.5 as the
elevation at which to calculate the forebay volume of Forebays B-D.
3. There is a statement on the deed restriction document regarding the possibility of
changes to the lot numbering. Please remove this statement, as any changes to
the lot numbers must be submitted as a plan revision. W I k- c+,,,,ft-e-AtA6 ­i
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received in this Office prior to December 30, 2007, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee,
If you need additional time to submit the information, please mail, email or fax your request for
a time extension to the Division at the address and fax number at the bottom of this letter. The
request must indicate the date by which you expect to submit the required information. The
Division is allowed 90 days from the receipt of a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.

The Hamptons Phases I & II (formerly Brunswick Plantation North)
Brunswick County
Dear Mr. McLamb:
The Wilmington Regional Office received a modified Stormwater Management Permit
Application for The Hamptons Phases I & II on June 27, 2007. A preliminary review of that
information has determined that the application is not complete. The following information is
needed to -continue the stormwater review:
1. Only a person who is at least the vice president in the corporation may sign the
permit application. Your signature can be accepted only if accompanied by a
signed letter from a person of at least the level of vice president in the
corporation, authorizing you to sign the application on behalf of the corporation.
2. There is a supplement for Pond 5, but no calculations have been provided.
3. There are some inconsistencies between the calculations and the supplements
regarding the permanent pool volume and the forebay volume for Ponds 1, 4, 6,
& 8. Except for Pond 8, these are multiple forebay ponds. The permanent pool
volume is that volume contained in the pond & forebays between the bottom and
the permanent pool elevation. Some forebays appear to have higher permanent
pool elevations than the pond. Use the same pond elevations in each forebay to
determine the volume in the forebays. The calculations also appear to exclude
some of the forebays. If you don't include all of the forebays in the forebay
volume calculation, don't use all the forebays for the overall surface area or
permanent pool volume calculations, either.
4. The calculations for Ponds 4 and 6 each mention a "West Pond" in their surface
area and volume totals, but no separate areas or volumes have been provided
which are labeled as "West Pond".
5. Please specify the wetlands species to be planted on the vegetated shelf.
6. Please check the addition for Forebays A & B of Pond 6. When I add up the
numbers in the calculations, I get 2,434,050, not 1,955,083.
7. For Pond 8, only the volume of Forebay #1 was reported on the supplement. The
forebay volume provided to report on the supplement should be the total volume
in both Forebay #1 and Forebay #2, or 201,201.

8. Please complete, sign, date, notarize and return the attached deed
restriction document.
9. On sheet 8, the label for the Pond 6 outlet structure says a 4.3" orifice
instead of 4 each @3".
10. Please set the weir elevation for the forebay outlet structure in Pond 6 to
the temporary pool elevation of 27.8. It is currently proposed to be 28.0.
11. Please move the outlet structure detail for Pond 6 to sheet 31.
12. Is there supposed to be a forebay outlet structure located between Lots
107 & 108? If so, please label.
13. Forebays B, C & D for Pond 1 have permanent pool elevations that are
higher than the permanent pool for Pond 1. These elevations need to
match.
14. Forebay C for Pond 4 has a permanent pool at 28 instead of 27.
Please note that this request for additional information is in response to a preliminary
review. The requested information should be received in this Office prior to October 5,
2007, or the application will be returned as incomplete. The return of a project will
necessitate resubmittal of all required items, including the application fee.
If you need additional time to submit the information, please mail, email or fax your
request for a time extension to the Division at the address and fax number at the bottom

required information. The Division is allowed 90 days from the receipt of a completed
application to issue the permit.

In accordance with Title 15 NCAC 2H.1000, the Coastal Stormwater Management Regulations, deed
restrictions and protective covenants are required for High Density Residential Subdivisions where
lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility.
Deed restrictions and protective covenants are necessary to ensure that the development maintains a
"built -upon" area consistent with the design criteria used to size the stormwater control facility.
I, acknowledge, affirm and agree by my signature below, that
I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot:
1. The following covenants are intended to ensure ongoing compliance with State Stormwater
Management Permit Number as issued by the Division of Water Quality
under NCAC 2H.1000.
2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to
maintain compliance with the stormwater management permit.
3. These covenants are to run with the land and be binding on all persons and parties claiming
under them.
4. The covenants pertaining to stormwater may not be altered or rescinded without the express
written consent of the State of North Carolina, Division of Water Quality.
5. Alteration of the drainage as shown on the approved plan may not take place without the
concurrence of the Division of Water Quality.
6. The maximum allowable built -upon area per lot is square feet. This allotted
amount includes any built -upon area constructed within the lot property boundaries, and that
portion of the right-of-way between the front lot line and the edge of the pavement. Built upon
area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate,
coquina and parking areas, but does not include raised, open wood decking, or the water
surface of swimming pools.
OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the
following:
6. The maximum built -upon area per lot, in square feet, is as listed below. -
Lot # BUA Lot # BUA Lot # BUA Lot # BUA
This allotted amount includes any built -upon area constructed within the lot property boundaries,
and that portion of the right-of-way between the front lot line and the edge of the pavement. Built
upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate,
coquina and parking areas, but does not include raised, open wood decking, or the water
surface of swimming pools.
7. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be
accomplished through a variety of means including roof drain gutters which drain to the street,
grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff
and directing them into a component of the stormwater collection system. Lots that will naturally
drain into the system are not required to provide these additional measures.
